Actually, Canada was a part of a very lengthy and intense competition to choose the company to build the joint strike fighter program. It was a U.S.-led competitive process. There were two companies, Boeing and Lockheed Martin, that put forward prototypes, and Lockheed Martin won the design phase to be the supplier to build the joint strike fighter.
Two years ago the air force, through the Canada First defence strategy, made a policy commitment to replace the CF-18s with a next-generation fighter. We have since done the research to ensure that the F-35 is the only aircraft that meets the requirements of the air force. Because we're part of the MOU for the joint strike fighter, we're able to use the MOU to procure these aircraft.
